C++ OpenCV 使用 resize() 调整图像大小
Mat Visible= imread("../pic/rgb_1.jpg"); //右图
Mat Infrared = imread("../pic/infrared_1.jpg"); //左图
if (Visible.empty() || Infrared.empty()) {cout << "could not load the image..." << endl;return -1;
}
Mat vis_1,infra_1;//裁剪
// vis_1 = Visible(Rect(0,0,600,600));
// infra_1 = Infrared(Rect(0,0,600,600));
//resize调整大小
resize(Visible,vis_1,Size(600,600));
resize(Infrared,infra_1,Size(600,600));参考：C++ OpenCV 使用 resize() 调整图像大小_opencv resize-CSDN博客
